Govt of Canada Historical Weather data
Data is collected from:
http://climate.weather.gc.ca/historical_data/search_historic_data_e.html

Data is available from the government on a daily basis and updated occasionally here. ;)

Date range currently covered:

Earliest date: 1970-01-01
Most recent date: 2021-07-04

The following weather stations are represented. Not the preferred approach but I couldn’t find continuous data for any single weather station.
